Introduction to Flask and Crimson Tears

Flask is a lightweight and flexible Python web framework that has gained popularity in recent years due to its simplicity and ease of use. Flask is a microframework, which means it doesn’t require you to create a full-fledged web application from scratch. Instead, it provides a set of pre-built components that you can use to build web applications quickly and efficiently.

Getting Started with Flask

Before we dive into the world of Crimson Tears, let’s cover the basics of using Flask. Here are the steps to get started:

• Install Flask using pip: pip install flask
• Create a new Python file for your Flask app: touch app.py
• Import Flask and create a new application instance: from flask import Flask; app = Flask(__name__)
• Define a route for your application: @app.route('/')
• Use the render_template function to render an HTML template: return render_template('index.html')

Basic Flask Concepts

Here are some basic concepts you should understand before moving on to Crimson Tears:

• Routes: Routes are the URLs that your application responds to. You can define multiple routes in your application using the @app.route() decorator.
• Templates: Templates are HTML files that contain the structure and content of your web pages. You can use the render_template() function to render a template in your application.
• Models: Models are classes that represent your data. You can use Flask-SQLAlchemy to interact with your database.
